I have learned (don't remember sources offhand) that raw food is not preferable for mishloach manos, because it isn't edible.
I was wondering if the same would apply to giving frozen food as mishloach manos.
My reason for wondering is that, on the one hand it would be the same as raw food in that the recipient cannot eat it as it is received. But on the other hand, he doesn't have to do anything to it to make it edible - just wait and it will be edible.
My question is both if it will defrost by the end of the day of Purim or even if it won't.
I already asked my Rabbi and got my answer, so this isn't a practical question - I am only interested to try and find sources who discuss it. My googling attempts came up dry.
